JAQUELIN S. HOLLIDAY, OF INDIANAPOLIS, INDIANA.

HORSESHOE-CALK. V

Specification of Letters Patent. Patentgd 9 9291116 1913, Applicationfiled February 11, 1913; Serial No. 747,679;

Z '0 all whom it may concern Be it known that I, JAQUELIN S. Hour DAY, acitizen of the United States, residing at Indianapolis, in the county ofMarion and State of Indiana, have invented certain new and usefulImprovements in Horseshoe- Calks, of which the following is aspecification.

The object of this invention is to provide a calk for a horseshoe havingwelding lugs thereon, which, when the calk is positioned on the red hotshoe, may be readily driven into the soft hot metal to position thecalk, and in which the welding lugs are shaped in such a manner thatwhen they are completely embedded in the hot metal of the shoe by thedriving home of the calk, points on the welding lug will be caused todiverge from each other thereby widening the inner ends of the weldinglugs and locking the calks in the desired position on the shoe. The calkthus locked to the shoe will retain its position on the latter duringits subsequent heating, and welding operation.

I accomplish the objects of the invention by the means shown in theaccompanying drawing, in which I Figure 1 is a side view of a calk forthe toe of a horseshoe, embodying my invention. Fig. 2 is an end view ofsame. Fig. 3 is a view in front elevation and partial vertical sectionof a horseshoe and my improved toe calk, showing the welding lug partlydriven home into the shoe, and Fig. 4 shows the horseshoe in like viewand section with the calk in contact with the shoe and the welding lugin its finished holding position.

Like characters of reference indicate like parts throughout the severalviews of the drawing.

7 The calk 4 is of the usual form for horseshoe toe calks, and has awelding lug on the face which is to contact with the horseshoe.

5 is the horseshoe, shown in the drawings in an inverted position fromthat in which the shoe is worn on the hoof of the horse, but in theposition in which the shoe is most conveniently held by the blacksmithduring the operation of welding on the calk. The welding lug preferablycomprises a body portion of thin material with opposite parallel sidesor sides which taper slightly, as shown in Fig. 2 of the drawings, tomake it enter the shoe more readily. This body portion terminates withtwo barbs or points 5 and 6, preferably of different lengths. The longerpoint 5 has an outer edge at right anglesto the face of the calk 4 towhich it is attached, and it has an oblique opposite edge whichintersects the adjacent oblique inner edge of the shorter point 6. Theopposite edge of the calk 6, being the inner edge of the welding lug asa whole, as here shown, is at right angles to the adjacent face of thecalk, and parallel with the outer edge of the lug.

The welding lugs, as above described, are preferably located at one sideof the middle of the calk, as shown.

In applying a calk of the above character to a horseshoe, the shoe isfirst heated to a temperature which will permit the welding lug of thecalk to be readily driven into it. The calk, still cold, is then placedin position upon the shoe resting upon the point 5 of the welding lugand upon the edge 7 of the opposite end of the calk. Then by strikingthe calk with a hammer opposite the welding lug the latter is driveninto the relatively soft metal ofthe shoe. The point 5 first penetratesthe soft metal to the position shown in Fig. 3 which quickly locates thecalk. Then the further progress of the welding lug causes the point 6 toenter the shoe and because of the parallel outer edges of the lug andoblique inner edges of the two points 5 and 6 the metal displaced tomake room for the points 5 and 6 will be crowded into the crotch of thetwo points where, by the further progress of the welding lug into thesoft metal of the hot shoe, the points 5 and 6 will be bent in oppositedirections by the pressure against their inner edges of the compactedmetal of the shoe, with the result that the welding lug will bebroadened by the spreading of the points, and the calk thereby securelylocked in position on the shoe, as is desired for the further operationsof heating both calkand shoe and the welding of same together.

While I have described my invention with more or less minuteness asregards details of construction and arrangement and as being embodied incertain precise forms, I do not desire to be limited thereto unduly orany more than is pointed out in the claim. On the contrary, Icontemplate all proper changes in form, construction and arrangement,the omission of immaterial elements and the substitution of equivalentsI my hand and sealat Indianapolis, Indiana, 15

I clalmz ing-a lug on one face, said lug having outside edgessubstantially perpendicular to the face of the calk and a pair of pointsformed 7 by a single V-shaped indent between the Copies of this patentmay be obtained for five c'entseach, by addressing the side edges of thepoints, one of which points is longer than the other.
